2023-04-13Support sdk_version for java/android/kotlin targets.Romain Jobredeaux
This CL: - Defines a host-only java toolchains with support for switching versions - registers a device and host java toolchains whose attributes depend on java_version, sdk kind and sdk api level build settings. - creates java/android/kotlin rule wrappers that enforce the sdk_transition based on sdk_version and java_version. - enables platform-based toolchain resolution for the android rules.

2023-03-17Switch away from local_jdk (to jdk17)Romain Jobredeaux
the @local_jdk repository does not support platform-restrictions, which will become an issue when needing to switch java toolchains based on platform. In addition, there's a bit of inconsistency currently between usages of jdk17 and jdk11, as the default java home is set to jdk17 but we use some custom targets in prebuilts/jdk/jdk11. This CL has bazel stop using the local_jdk and instead specify a local_java_runtime under prebuilts/jdk/jdk17, which we'll be able to impose platform restrictions on later. The Kotlin rules directly refer to @local_jdk//jar, so a stub local_jdk repository is defined to keep this reference valid.

2023-01-05Support multiple android products in a single bazel buildCole Faust
We create an android_product macro that replaces a lot of the existing platform code. It takes a soong.variables file, and creates bazel platforms for the android product, various other arches, and the host platforms. (currently host builds still depend on product config variables) To change products, you'll be able to pass --platform=//build/bazel/product_config/generated/products/<product_name>, however currently we only generate the platforms for the currently lunched product for performance. When the other products are in starlark, we can allow using all of them. Bug: 249685973 Test: Presubmits Change-Id: Ic1b0942a60c66eb3fe2b1aa7a2ff436ec9b3c3fb

2022-12-12Add transition for fdo profile to cc_library_sharedVinh Tran
Add transition to cc_library_shared to propagate fdo profile (set by fdo_profile attr) to static deps. The analysis tests ensures that the profile doesn't get propagated into shared deps. _fdo_profile_transition_correctly_set_and_unset_fdo_profile ensures the bug in bazel config causing duplicated deps is fixed by aosp/2305841.

2022-11-16Add --experimental_output_directory_naming_scheme=diff_against_baselineVinh Tran
Adding the experimental flag to get rid of the no-op "affected by Starlark transition" in Bazel config when a label-based flag (i.e. //command_line_option:fdo_profile) is set back to None. We have an incoming transition attached to a rule (i.e. _cc_library_shared_proxy) (aosp/2301014) such as ``` def _fdo_profile_transition_impl(_, attr): return { "//command_line_option:fdo_profile": getattr(attr, "fdo_profile"), } ``` which sets `//command_line_option:fdo_profile` to the value of `fdo_profile` attr. Say we have this dependency chain: ``` _cc_lib(name = "a") -> _cc_lib(name = "b", "fdo_profile" = ":fdo") -> _cc_lib(name = "c") ``` Even though the incoming transition ensures that `a` and `c` are built without `fdo_profile`, they're built with different configs. ``` INFO: Displaying config with id d1e8282 (a) affected by starlark transition: [] fdo_profile: null INFO: Displaying config with id 3cfee49 (b) affected by starlark transition: [//command_line_option:fdo_profile] fdo_profile: //:foo INFO: Displaying config with id 1598102 (c) affected by starlark transition: [//command_line_option:fdo_profile] fdo_profile: null ``` The flag make sures "affected by starlark transition" is empty the whole time so that the configs of `a` and `c` converge. Test: cherry-pick aosp/2301014 and b build //external/jsoncpp:libjsoncpp which doesn't set fdo_profile but its dep (i.e. //external/libcxx:libc++) does Change-Id: Icd5b225615de45a7cf026cbb66568a5b6fe7f85b
2022-10-13Move --package_path configs to bazel.sh to support $OUT_DIR != "out".Jingwen Chen
Currently, the bazelrc hardcodes the --package_path for queryview, bp2build and api_bp2build generated workspaces under "$TOP/out", the default $OUT_DIR. However, if $OUT_DIR is set to something else, these flags will break. To fix that, we generate the configs dynamically pointing to the absolute paths ($ABSOLUTE_OUT_DIR). Note that if $OUT_DIR is set to a directory under /tmp, Bazel errors out because it's incompatible with --sandbox_tmpfs_path=/tmp (see b/253396003) Bug: 251436403 Bug: 253396003 Test: new integration tests (see associated change in this topic) Change-Id: Id535d79b7ae12b0eaf73e6edbe3da65db7a5d7e4

2022-09-16Merge "Delete ResultStore bazelrc config."Treehugger Robot
2022-09-09Change the default --platforms to host, and restrict the allowedJingwen Chen
--platforms values. The current set of allowed --platforms are: - //build/bazel/platforms:linux_x86_64 (default) - //build/bazel/platforms:android_target (infers from product config - variables, i.e. lunch) This list is enforced by the startup --invocation_policy flag. An invalid --platforms value results in: ERROR: Flag value '[//build/bazel/platforms:android_arm64]' for option '--platforms' is not allowed by invocation policy and the policy does not specify a new value. Allowed values are: [//build/bazel/platforms:android_target, //build/bazel/platforms:linux_x86_64] This will prevent undefined behavior, such as `lunch aosp_arm && b build --config=android_x86_64`. Given that the host platform is now default, all android cross compilation commands need to pass --config=android to succeed. The other platform definitions aren't deleted yet because they're needed for split transition configuration (e.g. see apex_aab).

2022-01-17Implement a (partial) cc_stub_library rule for cc_library.stubs inJingwen Chen
Android.bp file. This rule is responsible for emitting an object generated from a .map.txt files for symbols associated to a shared library for a particular API level. These libraries set the "stubs" property in their Android.bp definitions. These libraries are used as build-time dependencies of Mainline modules (not the platform, i.e. NDK!). For stub libraries in the NDK, see ndk_library modules). These dependencies are *not* included in the Mainline modules themselves, because the non-stub versions are made available in the device environment through other means (e.g. installed onto the system partition or via other APEXes). These libraries are ABI stable. For this CL's scope, we introduce a new rule that calls ndkstubgen, a python binary, on a library's .map.txt file, which is actually in the format of a LD version script, to generate a .c file containing function prototypes, and two additional metadata files. The .c file would be eventually compiled into a stub .so, replacing the real .so for APEX dependents. The stub .so will be made available through a dedicated cc_shared_library_proxy provider so dependents can easily determine if a transitive dep has stubs for a requested API level.
